Prosperity is the surest breeder of insolence I know.

Pessimism is only the name that men of weak nerve give to wisdom.

It takes your enemy and your friend, working together, to hurt you to the heart: the one to slander you and the other to get the news to you.

I never could keep a promise. I do not blame myself for this weakness, because the fault must lie in my physical organization. It is likely that such a very liberal amount of space was given to the organ which enables me to make promises that the organ which should enable me to keep them was crowded out. But I grieve not. I like no half-way things. I had rather have one faculty nobly developed than two faculties of mere ordinary capacity.

It makes one hope and believe that a day will come when, in the eye of the law, literary property will be as sacred as whiskey, or any other of the necessaries of life. It grieves me to think how far more profound and reverent a respect the law would have for literature if a body could only get drunk on it.

The wise thing is for us diligently to train ourselves to lie thoughtfully, judiciously; to lie with a good object, and not an evil one; to lie for others' advantage, and not our own; to lie healingly, charitably, humanely, not cruelly, hurtfully, maliciously; to lie gracefully and graciously, not awkwardly and clumsily; to lie firmly, frankly, squarely, with head erect, not haltingly, tortuously, with pusillanimous mien, as being ashamed of our high calling.

Never run after you own hat - others will be delighted to do it; why spoil their fun?
